Transfer and routing of Gaussian states through quantum complex networks with and without community structure
Markku Hahto, Johannes Nokkala, Guillermo García-Pérez +2
The goal in quantum state transfer is to avoid the need to physically transport carriers of quantum information. This is achieved by using a suitably engineered Hamiltonian that in…
Thermodynamic fingerprints of non-Markovianity in a system of coupled superconducting qubits
S. Hamedani Raja, M. Borrelli, R. Schmidt +2
The exploitation and characterization of memory effects arising from the interaction between system and environment is a key prerequisite for quantum reservoir engineering beyond t…
Remote polarization entanglement generation by local dephasing and frequency upconversion
S. Hamedani Raja, G. Karpat, E. -M. Laine +4
We introduce a scheme for remote entanglement generation for the photon polarization. The technique is based on transferring the initial frequency correlations to specific polariza…
Frozen discord in non-Markovian dephasing channels
L. Mazzola, J. Piilo, S. Maniscalco
We investigate the dynamics of quantum and classical correlations in a system of two qubits under local colored-noise dephasing channels. The time evolution of a single qubit inter…
Phenomenological memory-kernel master equations and time-dependent Markovian processes
L. Mazzola, E. -M. Laine, H. -P. Breuer +2
Do phenomenological master equations with memory kernel always describe a non-Markovian quantum dynamics characterized by reverse flow of information? Is the integration over the p…
Cavity losses for the dissipative Jaynes-Cummings Hamiltonian beyond Rotating Wave Approximation
M. Scala, B. Militello, A. Messina +3
A microscopic derivation of the master equation for the Jaynes-Cummings model with cavity losses is given, taking into account the terms in the dissipator which vary with frequenci…
Misbelief and misunderstandings on the non--Markovian dynamics of a damped harmonic oscillator
S. Maniscalco, F. Intravaia, J. Piilo +1
We use the exact solution for the damped harmonic oscillator to discuss some relevant aspects of its open dynamics often mislead or misunderstood. We compare two different approxim…
Quantum theory of heating of a single trapped ion
F. Intravaia, S. Maniscalco, J. Piilo +1
The heating of trapped ions due to the interaction with a {\it quantized environment} is studied {\it without performing the Born-Markov approximation}. A generalized master equati…
